Abstract
A hub adapter used to modify a bicycle wheel hub to provide for the mounting of a disc brake rotor and/or for the repositioning of the wheel spoke mount flange to accommodate the additional components of a disc brake system. The hub adapter may be fixed to the host non-disc wheel hub by fastening bolts passing through the original spoke mounting holes or by other fastening means. The hub adapter may provide standard mounting holes for a disc brake rotor to be fixed to the hub adapter with fastening bolts. The hub adapter provides alternate spoke mounting holes on an alternate spoke flange, positioned in such a way so as to provide adequate clearance for disc brake components such as the disc brake caliper assembly, or in such a way as to change the length of the spokes and to modify the wheel stiffness. The hub adapter effectively becomes integral to the host wheel hub and critical to the primary function of the wheel hub, that is transferring load from the frame to the wheel.
Description
HUB ADAPTER FOR A BICYCLE DISC BRAKE
RELATED APPLICATIONS
This application claims t;he benefit of Provisional Patent Application No. 60/346,276, f-_led January 9, 2002, by Eric Goss and Daryl Musselman, entitled HUB ADAPTER FOR BICYCLE DISC BRAKE.
FIELD OF THE INVENTION
This invention relates, in general, to wheel hubs and to the mounting of disc brake sy::,tems on wheel hubs that were not specifically designed to receive disc brake system components.
BACKGROUND OF THE INVENTION
Bicycles delivered prior to 1996, especially mountain bikes, were most often equipped with V-brakes or rim-brakes where a cable actuated cantilever system effectively pinched the wheel rim between two rubber brake ~>ads. Bicycle: equipped with such brakes were also equipped wit.li non-disc wheel hubs.
Alternatively, bicycle disc-bLake system: ut=ilize a frame mounted caliper assembly that squeezer brake pads on a dedicated brake rotor, similar to systems used on modern moi=orcycles and automobiles. By 2002, than mayority of h:igh--end mountain bikes were sold with disc brake systems a~ standard equipment.
Bz.cycles equipped with sucvh disc-brake systems are equipped with disc-ready wheel hubs, designed ~>pecifically to accept the mounting of a dedicated brakfv rotor. Moving into the future, both rim-brake systems and disc-brake systems will continue to share the market and wheel hub manufacturers will continue to satisfy the needs of both competing systems.
The primary function of a wheel hub is to transfer the load of the vehicle and operator, the stationary part, to the rotating wheel, the moving part, throt:.gh a wheel bearing assembly. In the case of bicycles, this load transfer is generally accomplished by a single piece wheel hub to v,,hich wheel spokes are attached, and within which wheel bearings ure housed. Currently manufacturers generally supply two different types of wheels and/or hubs, one being non-disc wheels or hubs (i.e. wheels/hubs not designed to mount a disc brake rotor) anG the other being disc wheels or hubs (:i.e. wheels/hubs designed to mount a disc brake rotor).
Accordingly there is a need for a means for adapting non-disc wheels and hubs to disc urheels and =tubs .
SLlI~lARY OF THE INVENTION
The present invention relates to a hub adapter for adapting a non-disc specific ~.,~heel hub to securely mount a disc brake rotor, to modify the sp~>ke mounting position so as to provide clearance for ot:hex~<~isc brake system components, such as tine disc brake caliper assemb'~y, ~~nc~ to modify r_he performance of the wheel assembly. The hub .-~dapt:er: has a 'nub mounting face for fastening said hub adapter to said r:ub, an adapter spoke flange for fastening spokes of said wheel, and a rotor mounting face for fastening said rotor to said rLUb adapter.
The rotor mounting face =s located to allow for the proper positioning and function of the disc brake rotor within the disc brake caliper assembly. Furthermore, the rotor mounting face provides fastening points that are used t:o ~;ecure the disc brake rotor.
The new spoke mounting flange is located so as to position the wheel spokes in such a way as to eliminate any potential interference between the wheel spokes and a disc brake caliper assembly. Furthermore, this flange may be located in such a way as to modify the performance c;f the wheel by affecting its stiffness and/or lateral st.abil.ity.
The hub adapter is securEly fastened to the host wheel hub in such a way as to become intE=gral to the host wheel hub. In the preferred embodiment, thrE~aded holes in the hub adapter are located in alignment with holes on the spoke flange of the host wheel hub. Threaded fasteners pass through the holes on the spoke flange of the host wheel. hub and are threaded into the holes provided in the hub ada~>ter to securely fasten the hub adapter to the host wheel hub. 'The invention is not specific to any particular brand or model of wheel hub. In addition, the invention can be designed to fasten securely and function correctly in cooperation with many different types of bicycle wheel hubs, and to ac<Jommodate many different types of disc brake calipers and components. Furthermore, the invention applies equally to both the front and rear wheels of bicycles as well as wheels of other vehicles, such as wheelchairs, etc.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Shown in Figure 1 is a hub adapter 10 ~~f the present invention. The hub adapter 1;i i.s shown fasr_.ened to a non-disc specific bicycle wheel hub 12 (i..e. the bicycle wheel hub 12 is not specifically designed to ,ccept a disc brake rotor . The disc brake rotor 14 is shown i=astened to the hub adapter 10 by threaded rotor fasteners 1E. The hub adapter 1.0 is shown fastened to the bicycle whee7_ hub 1~ b~,r threaded hub fasteners 18.
Figure 2 i.s an e~:ploded ;sometric view of the various components shown in Figure 1. 'T'he bicyc7_e wheel hub 12 is inserted into the large centez hole 50 of. the hub adapter 10 so t~
as to allow the spoke flame ?8 on t:he bicycle wheel hub 12 to sit flush against the hub mounting face (not shown) of the hub adapter 10 and to be integral'~y secured by threaded hub fasteners 18. The threaded hub fasteners 18 are shown to pass through the spoke holes 20 on the bicycle wheel hub 12 <~nd into the threaded holes 34 on the hub adapter 1). I:t can be appreciated that the spoke holes 20 are not: av<~ila':ole t:o receive wheel spokes when the bicycle wheel hub 12 and the mb ad~ipter 10 are fastened together. New spoke holes 22 are provided on hub spoke flange 30 of the hub adapter 10 to a1_lo~.v wheel_ spokes to be installed.
Figure 2 further show; t=t,~e threaded rotor fasteners 16 passing through existing hole:: 23 on the disc brake rotor 14 and into the threaded receiving h:~les 24 provided in the rotor mounting face of the rotor mounting flange 27. The disc brake rotor 14 then sits flush agai2st: t=he rotor mounting face 26 of the rotor mounting flange <'.7.
Figure 3 is a front p-'~an view of the various components shown in Figures 1 and 2. The disc brake rotor 14 is shown fastened to the hub adapter_ 17 by s:ix threaded rotor fasteners 16 located according to a recogn~_zed international industry standard. It can be apprecia;-ed th<.~t although this international industry standard fastener po:~it=ion is preferred, alternative fastener positions and/or quantity ~~ould. be conceived that would not depart from the inver~tio:l. h:Ls~~, th.e overall size of the brake rotor 14 may vary wit:hozt affecting the principle of the invention.
Figure 4 is a cross section view of the various components shown in Figures 1, 2 and 3, tah:en through line A-A of Figure 3.
The bicycle wheel hub 12 is shown in schematic cross-section, with no internal components shown.. The spoke flange 28 on the bicycle wheel hub 12 sits i=lush a<~ainst the hub mounting face 32 of the hub adapter 10 and t=he bicyc=Le wheel hub 12 and hub adapter 10 are secured by t=hreaded hub fasteners 18.
Figure 5 is a front p=Lan view of the hub adapter 10. The disc brake rotor mounting -ac-~ 26 o:E the rotor mounting flange 27 and the threaded receiving hole: 24 for fastening the disc brake rotor are visible. Behind the roi~o:r mounting flange 27 are the spoke holes 22 and threaded holes 3~~ for receiving the spokes and threaded hub fasteners, z:espect=ively (spokes and threaded hub fasteners not shown).
Figure 6 is a side view of the hub adapter 10, similar to that shown in Figure 5. Figure 6 shows that the disc brake rotor mounting face 26 is flat to a11_ow for proper installation of the disc brake rotor, (not sfio~an) whereas true surface of adapter spoke flange 30 may be taperEC~ to allow wheel spokes passing through the spoke ho1_es 22 tc. b~~ mounted ire the correct position and with minimal strain.
Figure 7 is a rear plain ~,riew of the hub adapter 10. Figure 7 shows the hub mounting face 32, on the hub adapter 10 to which the spoke flange 28 (Figure 4) mount=s. Threaded holes 34 are shown to which the threaded h~,zb fasteners 18 (see Figure 1) are secured. The spacing and pitch circle diameter of the threaded holes 34 match the location of t:he :poke holes 20 of the bicycle wheel hub 12 (see Figures 1 and 2). While eight threaded holes 34 are shown, any number of holes to a maximum equal to the number of spoke holes 20 (Figure 2) may be conceived. Figure 7 further shows that the new spoke ho:Les 22 provided on the hub adapter 10 are located at the same <angular spacing, but on a larger pitch circle diameter than the spoke holes 20 on the bicycle wheel hub 12, (see Figures 1 and 2) which coincide with the positions of the threaded recei~;ring holes 34.
Figure 8 is a cross-section view of the hub adapter 10, taken through line B-B of Figure 5. The hub mounting face 32 on the hub adapter 10 is shown to be tapered irr this instance, to match the shape of the mating surface of spoke flange 28 on the host bicycle wheel hub 12 (see Figures 1 and 4) so that the hub adapter 10 may be secure=ly fastened by threaded hub fasteners 18 (see Figures 1 and 2) to the host bicycle wheel hub 12 (see Figures 1 and 2).
Figure 9 is a side Ulan view of an alteernate embodiment of the present invention., shown as intended fc>r use on a front wheel of a bicycle. In this vE~rsic n the hub adapter 10' is shown g attached to a front bicycle wheel hub 12'. In a similar manner to that illustrated in Figure 1, a disc brake rotor 14 is shown fastened to the hub adapter- 10' by threaded rotor fasteners 16.
Figure 10 is a cross-section view taken through line C-C of Figure 9. In this embodiment the hub adapter 10' is shown to be similarly fastened to the host bicycle w:hee:1 hub 12' by threaded hub fasteners 18' passing t:hr:~uc~h the spoke holes on the existing spoke flange 28'. A signific.:~nt; ofj=set is shown between the existing spoke flange 28' of the ho:>t bicycle wheel. hub 12' and the new spoke flange 30' on t:ze hub adapter 10'. This offset is required to reposition the wheel. ~>pokes to allow for the clear mounting and operation of additional disc brake system components such as the disc brake caliper. Llnlike the embodiments of Figs.
1-8, the embodiment of Figs. 9 and 10 does not have a rotor mounting flange.
Figures 11a and 11b are of a cross-section view similar to Figure 10, but with a schematic representation of a disc brake caliper assembly and <~ wheel and spoke assembly added. Figure 11a shows how the wheel spoke: 36 would typically be mounted to a host non-disc bicycle wheel h.ab 1'<?', (i.e. a hub which is not specifically designed t:o accer:>t a disc brake rotor) . Figure 11b shows the same host bicycle wheel hub 12' with a hub adapter 10' installed along with other key components of a disc brake system sur_h as the disc brake rotor 14 and the disc brake caliper assembly 38. The new whee_L smokes 40 fastened to the spoke flange 28' of hub adapter 1.0' are shown to provide adequate clearance for the mounting and operation of the disc brake caliper assembly 38. The original- wheel spokes 36 (shown as ghost lines in Figure 11b) are shown to interfere with the mounting position of the disc bral~:e caliper assembly 38. It can also be seen in Figure 11b that the location of the disc brake rotor mounting face 26 (see Figures 2, 5, 6 and 8) determines the positioning of the disc brake rotor 14 within the disc brake caliper assembly 38. The location <~nd orientation of the rotor mounting face 26 and fastening points for the disc brake rotor 14 and the relocation of the wheel spoke flange 28' for brake caliper assembly 38 clearance are key elements of the present invention.
Figure 12 is a side view of an alternative embodiment of the invention applicable to wheel hubs comprising two components. In Figure 12 the hub adapter 40 is shown fastened to one such component 42. Although aot :>hown in Figure 12, the original wheel hub (non-disc wheel huJu) comprises t.wo hub components 42 fastened together along rE~sp~~ct.ive junction faces 60. With respect to the original non-~~isc hub (not shown), comprising two components 42 fasten.='d t.oc~et~~er, the bearing assembly is contained within the non-dis~.v hub in a manner similar to prior art hubs . Similarly, in t:he adapted disc zub :shown in Figure 12 , comprising hub adapter 40 fastened to component 42, the bearing assembly (not shown) is contained within the adapted disc hub.
Although in the embodimE~nt of Figure 12, junction face 60 lies at.
the centerline of the wheel, it is E=nvisioned that the junction face 60 could also be disp:Laced fr_orn the centerline. In this embodiment the hub adapter 40 repla~~es one hub component (not shown) and is fastened to the remaining hub component 42 by engaging the hub mounting face 62 of the adapter 40 with the junction face 60 of the component 42 using fasteners 58 or other means. Alternatively, the hub component 42 and adapter 40 could each be screw threaded such that they could be screwed together.
In the embodiment oi: Fig. 12 the hub adapter 40 is interchangeable with one of the two hub components 42, each of which comprises approximately- one half of_ a wheel hub. The hub adapter 40 does not engage the spoke flange of the host wheel hub 42 as in the embodiments of Figures 1, 2 and 4. The principle of the invention is maintained ~_n that the wheel hub (i.e. the host wheel hub component 42 and hi.ib adapter 40) is adapted to mount a disc brake rotor 14, and/or t.;he position of the spokes may be modified to accommodate the brake caliper assembly.
As in the previous ernbo<iiment:> discussed herein, the rotor 14 is fastened to the rotor :noun tang face :?6 of: the hub adapter 40 by threaded fasteners 16.
Figure 13 is a cross--se~:-tion view taken through line D-D of Figure 12. The inside details of: t=he host wheel hub 42 and the hub adapter 40 are shown >ch~emat:ucally only. The resulting adapted wheel hub is made up ~~f two separate pieces (40 and 42 in the configuration shown) fastened together.
The advantage of the embodiment: of Figures 12 and 13 is that host wheel hub may be manufactured in two identical parts, (each part being identical to host wheel hub component 42) either one of which is interchangeable with t=he hub adapter 40. In the embodiments described in Figures 1-11, the hub adapter 10, 10' is fastened to an existing standard wheel hub 12, 12' whereas in the embodiment of Figures 12 and 13 one wheel hub component 42 is replaced with the hub adapter 40. It can be foreseen that the embodiment shown in Figures 12 and 13 could be supplied to retailers and consumers as either a non-disc specific wheel hub, (i.e. a wheel hub compri~~ing a first wheel hub component 42 and a mirror of component 42), or as a disc specific wheel hub comprising a wheel hub component 42 and a hub adapter 40, with potential manufacturing cost savings to the manufacturer.
Although the in the emb<vdiments of Figs. 12 and 13 the host non-disc wheel hub comprises two substantially identical parts, (each part being substant=ial=,y similar too host wheel hub component 42) it wou7_d be readily apparent to those skilled in the art that the host non-di:~c wheel hub could be made of two hub components that differ in si_«e and/or shape.
A further embodiment of= the present invention is envisioned adaptation of wheels having :-~n i_ntegral hub (i.e. the hub, spokes t3 and rim form one piece). In such integral hub wheels, the position of the spokes obvio~zsly cannot be altered to accommodate a disc brake assembly and/or disc brake rotor, therefore, the hub adapter could only be used in those instances where there is sufficient clearance for the disc brake assembly and disc rotor.
In addition, alternative means fc>r fastening the hub adapter to the hub may be necessary, since ~;uch integral hub wheels do not have spoke flanges 2~~ or holE~s 20 =;uch as those shown in Figure 2. For example the hub adapr_er may be bonded to the integral hub wheel using structural adhes:.~re, or the hub adapter may comprise two complementary halves t.hat~ may be fastened together about the hub of the integral hub whee:.
Although various embodinnent~> of the present invention have been described in the contex~~ of their_ appLicat=ion to bicycle wheels, this invention is ob-.Tiou~>ly applicable to wheels of other vehicles (e. g. wheelchairs).
Accordingly, while this invention has been described with reference to illustrative emoocliments, this description is not intended to be construed in ,~ limiting sense. Various modifications of the illu~>trative embodiments, as well as other embodiments of the invention, wi7_1 be apparent to persons skilled in the art upon reference to thi:> c~escripti.on. It is therefore contemplated that th<-~ appended c~~_aims will cover any such modifications or embodiment: a'> fa=Ll within the true scope of the invention.

The bicycle wheel hub 12 is shown in schematic cross-section, with no internal components shown.. The spoke flange 28 on the bicycle wheel hub 12 sits i=lush a<~ainst the hub mounting face 32 of the hub adapter 10 and t=he bicyc=Le wheel hub 12 and hub adapter 10 are secured by t=hreaded hub fasteners 18.
Figure 5 is a front p=Lan view of the hub adapter 10. The disc brake rotor mounting -ac-~ 26 o:E the rotor mounting flange 27 and the threaded receiving hole: 24 for fastening the disc brake rotor are visible. Behind the roi~o:r mounting flange 27 are the spoke holes 22 and threaded holes 3~~ for receiving the spokes and threaded hub fasteners, z:espect=ively (spokes and threaded hub fasteners not shown).
Figure 6 is a side view of the hub adapter 10, similar to that shown in Figure 5. Figure 6 shows that the disc brake rotor mounting face 26 is flat to a11_ow for proper installation of the disc brake rotor, (not sfio~an) whereas true surface of adapter spoke flange 30 may be taperEC~ to allow wheel spokes passing through the spoke ho1_es 22 tc. b~~ mounted ire the correct position and with minimal strain.
Figure 7 is a rear plain ~,riew of the hub adapter 10. Figure 7 shows the hub mounting face 32, on the hub adapter 10 to which the spoke flange 28 (Figure 4) mount=s. Threaded holes 34 are shown to which the threaded h~,zb fasteners 18 (see Figure 1) are secured. The spacing and pitch circle diameter of the threaded holes 34 match the location of t:he :poke holes 20 of the bicycle wheel hub 12 (see Figures 1 and 2). While eight threaded holes 34 are shown, any number of holes to a maximum equal to the number of spoke holes 20 (Figure 2) may be conceived. Figure 7 further shows that the new spoke ho:Les 22 provided on the hub adapter 10 are located at the same <angular spacing, but on a larger pitch circle diameter than the spoke holes 20 on the bicycle wheel hub 12, (see Figures 1 and 2) which coincide with the positions of the threaded recei~;ring holes 34.
Figure 8 is a cross-section view of the hub adapter 10, taken through line B-B of Figure 5. The hub mounting face 32 on the hub adapter 10 is shown to be tapered irr this instance, to match the shape of the mating surface of spoke flange 28 on the host bicycle wheel hub 12 (see Figures 1 and 4) so that the hub adapter 10 may be secure=ly fastened by threaded hub fasteners 18 (see Figures 1 and 2) to the host bicycle wheel hub 12 (see Figures 1 and 2).
Figure 9 is a side Ulan view of an alteernate embodiment of the present invention., shown as intended fc>r use on a front wheel of a bicycle. In this vE~rsic n the hub adapter 10' is shown g attached to a front bicycle wheel hub 12'. In a similar manner to that illustrated in Figure 1, a disc brake rotor 14 is shown fastened to the hub adapter- 10' by threaded rotor fasteners 16.
Figure 10 is a cross-section view taken through line C-C of Figure 9. In this embodiment the hub adapter 10' is shown to be similarly fastened to the host bicycle w:hee:1 hub 12' by threaded hub fasteners 18' passing t:hr:~uc~h the spoke holes on the existing spoke flange 28'. A signific.:~nt; ofj=set is shown between the existing spoke flange 28' of the ho:>t bicycle wheel. hub 12' and the new spoke flange 30' on t:ze hub adapter 10'. This offset is required to reposition the wheel. ~>pokes to allow for the clear mounting and operation of additional disc brake system components such as the disc brake caliper. Llnlike the embodiments of Figs.
1-8, the embodiment of Figs. 9 and 10 does not have a rotor mounting flange.
Figures 11a and 11b are of a cross-section view similar to Figure 10, but with a schematic representation of a disc brake caliper assembly and <~ wheel and spoke assembly added. Figure 11a shows how the wheel spoke: 36 would typically be mounted to a host non-disc bicycle wheel h.ab 1'<?', (i.e. a hub which is not specifically designed t:o accer:>t a disc brake rotor) . Figure 11b shows the same host bicycle wheel hub 12' with a hub adapter 10' installed along with other key components of a disc brake system sur_h as the disc brake rotor 14 and the disc brake caliper assembly 38. The new whee_L smokes 40 fastened to the spoke flange 28' of hub adapter 1.0' are shown to provide adequate clearance for the mounting and operation of the disc brake caliper assembly 38. The original- wheel spokes 36 (shown as ghost lines in Figure 11b) are shown to interfere with the mounting position of the disc bral~:e caliper assembly 38. It can also be seen in Figure 11b that the location of the disc brake rotor mounting face 26 (see Figures 2, 5, 6 and 8) determines the positioning of the disc brake rotor 14 within the disc brake caliper assembly 38. The location <~nd orientation of the rotor mounting face 26 and fastening points for the disc brake rotor 14 and the relocation of the wheel spoke flange 28' for brake caliper assembly 38 clearance are key elements of the present invention.
Figure 12 is a side view of an alternative embodiment of the invention applicable to wheel hubs comprising two components. In Figure 12 the hub adapter 40 is shown fastened to one such component 42. Although aot :>hown in Figure 12, the original wheel hub (non-disc wheel huJu) comprises t.wo hub components 42 fastened together along rE~sp~~ct.ive junction faces 60. With respect to the original non-~~isc hub (not shown), comprising two components 42 fasten.='d t.oc~et~~er, the bearing assembly is contained within the non-dis~.v hub in a manner similar to prior art hubs . Similarly, in t:he adapted disc zub :shown in Figure 12 , comprising hub adapter 40 fastened to component 42, the bearing assembly (not shown) is contained within the adapted disc hub.
Although in the embodimE~nt of Figure 12, junction face 60 lies at.
the centerline of the wheel, it is E=nvisioned that the junction face 60 could also be disp:Laced fr_orn the centerline. In this embodiment the hub adapter 40 repla~~es one hub component (not shown) and is fastened to the remaining hub component 42 by engaging the hub mounting face 62 of the adapter 40 with the junction face 60 of the component 42 using fasteners 58 or other means. Alternatively, the hub component 42 and adapter 40 could each be screw threaded such that they could be screwed together.
In the embodiment oi: Fig. 12 the hub adapter 40 is interchangeable with one of the two hub components 42, each of which comprises approximately- one half of_ a wheel hub. The hub adapter 40 does not engage the spoke flange of the host wheel hub 42 as in the embodiments of Figures 1, 2 and 4. The principle of the invention is maintained ~_n that the wheel hub (i.e. the host wheel hub component 42 and hi.ib adapter 40) is adapted to mount a disc brake rotor 14, and/or t.;he position of the spokes may be modified to accommodate the brake caliper assembly.
As in the previous ernbo<iiment:> discussed herein, the rotor 14 is fastened to the rotor :noun tang face :?6 of: the hub adapter 40 by threaded fasteners 16.
Figure 13 is a cross--se~:-tion view taken through line D-D of Figure 12. The inside details of: t=he host wheel hub 42 and the hub adapter 40 are shown >ch~emat:ucally only. The resulting adapted wheel hub is made up ~~f two separate pieces (40 and 42 in the configuration shown) fastened together.
The advantage of the embodiment: of Figures 12 and 13 is that host wheel hub may be manufactured in two identical parts, (each part being identical to host wheel hub component 42) either one of which is interchangeable with t=he hub adapter 40. In the embodiments described in Figures 1-11, the hub adapter 10, 10' is fastened to an existing standard wheel hub 12, 12' whereas in the embodiment of Figures 12 and 13 one wheel hub component 42 is replaced with the hub adapter 40. It can be foreseen that the embodiment shown in Figures 12 and 13 could be supplied to retailers and consumers as either a non-disc specific wheel hub, (i.e. a wheel hub compri~~ing a first wheel hub component 42 and a mirror of component 42), or as a disc specific wheel hub comprising a wheel hub component 42 and a hub adapter 40, with potential manufacturing cost savings to the manufacturer.
Although the in the emb<vdiments of Figs. 12 and 13 the host non-disc wheel hub comprises two substantially identical parts, (each part being substant=ial=,y similar too host wheel hub component 42) it wou7_d be readily apparent to those skilled in the art that the host non-di:~c wheel hub could be made of two hub components that differ in si_«e and/or shape.
A further embodiment of= the present invention is envisioned adaptation of wheels having :-~n i_ntegral hub (i.e. the hub, spokes t3 and rim form one piece). In such integral hub wheels, the position of the spokes obvio~zsly cannot be altered to accommodate a disc brake assembly and/or disc brake rotor, therefore, the hub adapter could only be used in those instances where there is sufficient clearance for the disc brake assembly and disc rotor.
In addition, alternative means fc>r fastening the hub adapter to the hub may be necessary, since ~;uch integral hub wheels do not have spoke flanges 2~~ or holE~s 20 =;uch as those shown in Figure 2. For example the hub adapr_er may be bonded to the integral hub wheel using structural adhes:.~re, or the hub adapter may comprise two complementary halves t.hat~ may be fastened together about the hub of the integral hub whee:.
Although various embodinnent~> of the present invention have been described in the contex~~ of their_ appLicat=ion to bicycle wheels, this invention is ob-.Tiou~>ly applicable to wheels of other vehicles (e. g. wheelchairs).
Accordingly, while this invention has been described with reference to illustrative emoocliments, this description is not intended to be construed in ,~ limiting sense. Various modifications of the illu~>trative embodiments, as well as other embodiments of the invention, wi7_1 be apparent to persons skilled in the art upon reference to thi:> c~escripti.on. It is therefore contemplated that th<-~ appended c~~_aims will cover any such modifications or embodiment: a'> fa=Ll within the true scope of the invention.
